IMPROVEMENT IN DUMPlNG-WAGONS.

Specification forming part of Letters Patent No. 216,327, dated June 10, 1879; application filed April 1, 1879.

To all whom it may concern:

Be it known that I, LEvI JARMAN, of Moscow, Olermont county, Ohio, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specification.

This invention relates to those Wagons having movable beds or bodies capable of being shifted rearwardly and then tilted to discharge the load; and my improvements comprise a povel combination of devices for moving such weds.

The devices employedfor this purpose consist of a Windlass or drum journaled in the rear end of a suitable frame, and adapted to support the hind part of the bed or body of the wagon.

Furthermore, this Windlass has coiled around it a rope or chain, or other flexible coupling, that is secured to the bed in such a manner as to retract the latter as soon as the Windlass is properly rotated, which rotation may be effected with any convenient appliance.

I prefer, however, to use a lever, pawl, and ratchet-wheel, located at the side of the wagon, as hereinafter more fully described.

In the annexed drawings, Figure lis a side elevation, showing my improved dumpingwagon in its normal position, the runninggears of the vehicle proper being omitted. Fig. 2 is a longitudinal section through the same. Fig. 3 is a similar section, but showing the body tilted, one of the rear wheels of the vehicle being represented in this illustra tion. Fig. 4 is a plan of part of the main frame, and Fig. 5 is an enlarged elevation of the rear end of said frame and its accessories.

A B represent, respectively, the front and rear bolsters of any suitable wagon, and a a b b are the standards of the same. Adapted to rest upon these bolsters are two stout beams or sills, C 0, connected by cross-ties D D, which ties bear against said bolsters in the manner shown. The rear ends of these sills are furnished with boxes or other bearings c c for the journals of a stout drum, or cylinder, or indlass, E, having a collar, e, and a square arbor, e, which latter is secured within the flange or hub f of ratchet-wheel F, said wheel being preferably operated by the pawl g of lever G; but, if preferred, holes may be made in collar 6 to admit a capstan-ban'or the drum can be driven with gearing or other convenient appliances.

H is a strap or loop for maintainingthe lever G erect when not in. use. Attached to drum E is one end of a rope or chain, or other flexible coupling, I, whose other end is secured atJ to the shiftable body or bed K, which bed has a bottom, L, an end-gate, M, and two longitudinal rails, N N, said rails being adapted to slide between sills O O, as more clearly shown in Fig. 5. These rails rest upon drum E, and also upon rollers O O P P of shafts 0 p, which shafts are journaled in the aforesaid sills. Furthermore, shaft 0 is placed somewhat higher than the one 17 to impart a rearward pitch to body K.

R R are ropes or chains connecting said body to the sills O G, the object of these stays being to prevent the body becoming detached from the main frame when the load is dumped out. S is a bolt or pin passing through staple k of the body, and entering a socket, T, of sill O. U is one of the hind 'wheels of the wagon.

The body or bed K, when loaded and in its normal position, is secured by the retaining device S; but when it is desired to dump the load this bolt is withdrawn and loop H is disengaged from the lever G. The teamster now gives said lever a few strokes, so as to rotate drum E and coil the coupling I around the same. This operation retracts the body K, and as soon as it recedes far enough the load tilts it, as seen in Fig. 3, the stays R R preventing said body being completely detached from its supporting-frame O G. The load having been thus dumped, pawl g is thrown out of gear with ratchet F, and the now empty bed is readily shoved forward on the drum and small rollers, the ropeluncoiling accord ingly, and the stays R R assuming their slackened condition.

From the above description it will be seen that drum E serves as one of the rollers to support bed K, and consequently the rotation An obvious but inferlor modification of my invention may have the rollers O O P P applied to body K, and adapted to run on inclined tracks or ways secured to the sills O O.

I claim as my invention 1. In a dumping-wagon, the cylinder or drum E, serving the twofold purpose of a roller to support the rear end of the body K and a windlass around which is wound the chain or rope I, substantially as herein described.

2. An improved dumping-wagon, consisting of the Windlass E, ratchet-wheel F, lever Gr, pawl g, and rope or chain I, for retracting the shiftable bed K, which Windlass or drum serves as a roller to support the rear end of said bed, as herein described and set forth.

3. An improved dumping-wagon, consisting of the sills G O, Windlass E, ratchet-wheel F, lever Gr, pawl g, connection I, body or bed K, and rollers O O P P, the Windlass E being located at the rear end of said sills, and serving as a support for the bed, as herein de- Witnesses:
